Below in conjunction with the accompanying drawing in the embodiment of the present invention, to the skill of each exemplary embodiment provided by the present invention
Art scheme is clearly and completely described.In the case where not conflicting, following each embodiments and its technical characteristic can be mutual
Combination.
Fig. 1 is the schematic flow sheet of the method for the optimization voice command of first embodiment of the invention.Referring to Fig. 1, this reality
Step S11~S14 can be included by applying the optimization voice command method of example.
S11：Terminal receives or gathered from current environment audio signal.
In the present embodiment, terminal can obtain audio signal by two ways：
First, terminal is downloaded from network and high in the clouds, or received from the other equipment to be established a connection with terminal.Example
Such as, terminal can access network and high in the clouds by modules such as the bluetooth of itself, Wi-Fi and networks, or be built with other equipment
Vertical annexation, and thus obtain audio signal.Now, the audio signal that terminal obtains is digital audio and video signals.
Second, terminal gathers audio signal by sound pick-ups such as microphones from current environment.In the present embodiment, this is picked up
Sound device can be simulation microphone, and the audio signal that sound pick-up collects is simulated audio signal, it is exported and analog audio
Frequency signal, for the ease of subsequently carrying out various digital processings to audio signal, terminal can be by sound pick-up and analog-digital converter
(Analog-to-Digital Converter, ADC) is connected, after the analog-to-digital conversion that simulated audio signal passes through analog-digital converter
It is changed into digital audio and video signals, and continues to be transferred to the subsequent conditioning circuit of terminal to carry out various digital processings.Certainly, the present embodiment
Sound pick-up can also be digital microphone, and the great advantage of digital microphone is strong antijamming capability, without as traditional microphones
Built-in like that high-frequency filter capacitor and filter circuit, also, due to digital microphone output be digital audio and video signals, because
This terminal can be connected with subsequent conditioning circuit directly by sound pick-up and carry out various digital processings.
It should be understood that the sound pick-up of the present embodiment is including but not limited to above-mentioned.For example, terminal can also be by vibrating motor simultaneously
Audio signal is gathered from current environment based on counter electromotive force principle, specifically：Based on Faraday's electromagnetic induction law, vibration electricity
AC (Alternating Current, alternating current) signal in machine produces the magnetic field of change on coil, produces electromagnetic induction electricity
Kinetic potential, at the same time, people speak caused by audio signal air pressure is changed, shaken by vibrating surrounding air to cause
The diaphragm vibration of dynamic motor, based on lenz' law, impinged upon when being vibrated caused by vibration caused by audio signal and electromagnetic induction
During same diaphragm, external force direction that diaphragm is subject on the contrary, vibrating motor can produce the electromotive force opposite with electromagnetic induction electromotive force,
That is counter electromotive force.Digital audio and video signals are can obtain by monitoring electric current caused by counter electromotive force, and by electroacoustic conversion.Compare
Compared with microphone, the diaphragm effective coverage (region for being adapted to sound to hit) of vibrating motor is bigger, can capture wider frequency range
Audio signal, advantageously in improve voice command discrimination.
In the present embodiment, the target sound source in current environment (such as mankind) can play 20Hz-20kHz just
String ripple signal, the sound pick-up of terminal can move along netted route and gather the audio analog signals in current environment.Specifically,
As shown in Fig. 2 speaking on direction in target sound source, sound pick-up can move along progressively or column by column, and gather audio signal.

Resolved audio signal is digital audio and video signals, and the File header information of acquisition includes but is not limited to sample rate, ratio
At least one of special rate, bandwidth and data byte digit.
S13：Terminal chooses audio processing algorithms according to File header information.
What terminal was chosen to obtain is the audio processing algorithms most matched with the various data that File header information is included, the sound
Frequency Processing Algorithm processing audio signal efficiency and quality it is optimal, such as bandwidth expansion and frequency range compensation efficiency and quality most
It is good.Based on this, the present embodiment is not intended to limit the type of audio processing algorithms and its carries out bandwidth expansion and the principle of frequency range compensation
And process.
S14：Terminal is expanded the bandwidth of audio signal by the audio processing algorithms of selection, and to the sound after expansion
The frequency range of frequency signal carries out frequency range compensation.
In a kind of application scenarios, audio processing algorithms can be by audio signal (voice) in 20Hz-20kHz frequency range
Frequency modification is carried out to change its audio curve.For example, audio processing algorithms first by the audio signal collected from 8kHz bands
Pair width is extended for 16kHz, makes up the part voice of loss, then carries out frequency range compensation to the frequency range of wherein low sampling rate, i.e.,
Audio signal after expansion is repaired so that the part voice made up more conforms to actual voice feature.
From the foregoing, the present embodiment is essentially by pure algorithm process audio signal, to the degree of dependence of hardware compared with
Low, voice command discrimination can ensured using the high voice collecting device of performance, the present embodiment by being compared to prior art
While reduce hardware requirement, cost is low, and without in order to realize it is compatible whole hardware system is redesigned, it is general
Property is strong.
On aforementioned base, terminal can be based on speech recognition (Automatic Speech Recognition, ASR) technology
Audio signal after algorithm process is converted into character instruction.Speech recognition technology is to convert voice signals into the words such as word
The technology of symbol, it depends on acoustic model, pronunciation word library and language form storehouse.Wherein, acoustic model is that have by training
The statistical model of element, the phoneme of its audio signal after being handled by recognizer obtain corresponding aligned phoneme sequence, Ran Houben
These phonemes are compared in pronunciation word library for invention, list candidate word and the possible pronunciation of these candidate words, based on
The aligned phoneme sequence matched somebody with somebody, most possible word is selected from these candidate words, be ginseng in conjunction with the grammer included by language model
According to drawing character instruction.
Certainly, the audio signal after algorithm process can also be uploaded to high in the clouds by terminal.
If it should be appreciated that above-mentioned function is realized in the form of software function and sells or use as stand-alone product
